1)gain an equal amount of momentum during each second
2)gain an equal amount of kinetic energy during each second
3)gain an equal amount of speed for each meter it falls
4)gain an equal amount of momentum for each meter is falls
5)the amount of momentum it gains will be proportional to the amount of potential energy it loses.

the motion under gravity have some special assumption that at maximum height velocity will be zero and it will fall freely under gravitational acceleration
